House design
Who created the plan:
- Architect

What do you dislike? Why?: Currently, the upper floor has knee walls of 1.80m, but the windows cannot be opened (I find a fall protection unattractive) and I would also like shutters there. But then the window would only be 60cm high.... I cannot imagine how that would look.
Price estimate according to architect/planner: €380,000
Personal price limit for the house: €252,000 will be financed, the rest own contribution.
Preferred heating technology: geothermal heat pump

If you have to do without, which details/extensions
- can you do without:
- can you not do without: utility room with washing machine separately including exit to the yard.

Why is the design the way it is now? I specified rooms based on ideas and the architect implemented them.

What is the most important/basic question about the floor plan summarized in 130 characters? The window planning, I cannot imagine it.

Here are the pictures.

Where is the 3rd generation? I only see the 2nd.

Sorry, but what is that supposed to be with the 2 children's rooms of 31 and 36m²?
In return, you cram a bedroom with a double bed into 10m² and make a dressing room which can only be entered individually, because two people can't pass each other.

Sorry, but somehow it seems to me that the 3rd unit is rather a joke.
I don't want to accuse anyone, but the first thing that comes to mind is tapping into subsidies, which of course also increase with several units...

If I now assume that child 2 with bathroom 2 are supposed to form the 3rd unit, how do you get there?
Via the outside stairs?

About the ground floor:

Why do the utility room and HAR have to be separate? That doesn’t make things any easier.
And again a bedroom including closet with 12m².
For me, the proportions are completely off. Why not just put the office upstairs, and make the children's room smaller.
On the ground floor, combine utility room and HAR, then there’s a little more space for the bedroom and an "age-appropriate" bathroom.

Don’t be mad at me, but many things don’t add up for me...

Main house with a granny flat (=Child2 - is my older son) and age-appropriate extension (Grandma is moving in there). That makes 3. You can access the granny flat through the house and via the outside stairs (at the extension) over the roof terrace.

Take advantage of subsidies? I’m not even aware of any.

The utility room is purely the laundry room and the HAR houses the technology and storage stuff.
I don’t need anything age-appropriate in the main house.
The bedroom on the ground floor is initially the guest children’s room.
Upstairs I only want to sleep (for that I only need the bed) and the section for the wardrobes is not a dressing room (I don’t need something like that).
Child1 is consciously tall (after all, he plays a lot with Lego).

The site plan, north arrow, floor plan dimensions, etc. are missing. The plans are only very poorly legible. More targeted scanning of only the drawing area would make viewing easier, and appropriately rotating house views so that you don’t have to twist your neck in front of the screen would be simply nice ;). Where, for example, are the terraces, the 5 parking spaces, the street, etc.

Otherwise, I agree with Matte1987 .. everything is quite convoluted, for example the cloakroom and the pantry. It would probably be easier to make two straight separated areas there. Although I would check the pantry anyway ... given the kitchen size. Four dining seats are indicated .. does that mean in the dining room?

Parent sleeping area .. maybe it’s supposed to be just a walk-in closet, but the sleeping/closet solution is still not very pleasing. Just as little as the entrance to the Lego kids’ room of child 1.

The staircase from the ground floor to the upper floor ends right in front of the wall. That should actually be better solvable.

I also don’t find the apartment entrance of the granny flat with the bed right next to it (where should a cloakroom go?) very successful.

What is supposed to happen on the generation extension on the roof?

Regarding the knee wall of 180 ... that would absolutely not be my wish. The glass top edge of a window, even without a shutter, always ends at a maximum of about 160 cm height .. a no-go for people who are 180 cm tall. You walk into rooms and can’t look out of the window. And that also brings to mind the WCs on the upper floor. Urgently check the standing height there.

Price estimate according to architect/planner: €380,000 Personal price limit for the house: €252,000 is financed, the rest is self-performed.

Almost €130,000 of self-performance I find ambitious and should be achieved precisely how or do you mean equity? €380,000 total price as well. The house is overall relatively convoluted, has this large roof area with railing, etc.

Approx. 300m² living space for €380,000? Completely unrealistic
